9.17 DIGITAL VOICE OPERATION 
Digital voice programmed systems have two (2) different voice modes: clear (analog) and digital. The 
voice modes are programmed on a per-channel basis within each conventional system. 
9.17.1 Clear Mode 
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice 
signals. These analog signals are non-digitized. Clear mode transmissions can be monitored easily by 
unauthorized persons.  
 
Channels programmed for clear operation cannot transmit or receive digital signals. 
9.17.2 Digital Mode 
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide 
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and 
channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls) 
are answered back in the mode in which they were received assuming the call or hang time is still active.
